What is investment casting process?
Investment casting, also known as precision casting or lost-wax casting, is a manufacturing process in which a wax pattern is used to shape a disposable ceramic mold. A wax pattern is made in the exact shape of the item to be cast. This pattern is coated with a refractory ceramic material.
How do I design an investment cast?
Investment Casting Design Considerations
- Size and Weight. Part size and weight are the most critical factors in determining part cost because mold capacity is limited by both size and weight.
- Number of Gates. When possible, a part should be designed so that a single gate can feed the part.
What is investment casting Slideshare?
Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest known metal-forming techniques. It a technique for making small, accurate castings in refractory alloys using a mold formed around a pattern of wax or similar material which is then removed by melting. 3.
What are the steps involved in casting?
There are five steps in the casting process: patternmaking, molding, melting and pouring, shakeout, and heat treatment and inspection.
What is investment casting and name two type of materials that can be used for the pattern?
Investment casting is so named because the process invests (surrounds) the pattern with refractory material to make a mould, and a molten substance is cast into the mold. Materials that can be cast include stainless steel alloys, brass, aluminium, carbon steel and glass.
What is investment casting applications?
Investment casting is a metal working process that uses a ceramic shell built over a wax pattern to produce parts with extraordinarily uniform and smooth surfaces. The wax pattern is produced from an aluminum die.
What is investment casting and its application?
What is investment casting? Investment casting, which is also known as “lost wax” casting. it is a method of the precision casting process to manufacture small complicated parts, using almost all alloy. The process uses replication of wax patterns to create parts.
What is investment casting describe the complete step by step procedure of investment casting What are the main advantages and disadvantages of investment casting?
Advantages and disadvantages of investment casting
- Excellent surface finish.
- Tight dimensional tolerances.
- Complex and intricate shapes may be produced.
- Capability to cast thin walls.
- Wide variety of metals and alloys (ferrous and non-ferrous) may be cast.
- Draft is not required in the molds design.
- Low material waste.
What are the applications of investment casting?
The applications of investment castings are limitless. However, the aerospace, power generation, firearm, automotive, military, commercial, food service, gas and oil, and energy industries use these metal components the most.
